The reality of an invisible world surrounding the physical world is for many difficult to comprehend, since the mind sphere is often limited to the visible and tangible; however, it requires but little thought to realize the constant change of matter as it occurs in three forms, solid, liquid and gaseous, in its range back and forth between the visible and invisible.

Visible nature is but the invisible, the Real, made manifest through a combination of its elements; science informs us that fully ninety-five percent of vegetation is derived out of the air, or atmosphere. Is not mankind living at the bottom of an invisible ocean, the atmosphere, which is even more important to physical existence than any of the visible physical substances, since life can continue but a few moments out of it? Nitrogen gas, constituting the greater bulk of the atmosphere, enters vitally into vegetable and animal growth and existence. Hydrogen and oxygen gases are constantly changing from a state of invisible vapor to visible and solid form. Carbon offers another example of similar transformation. Sounds, odors, the thermic law of heat and cold and multitudes of other phenomena, ranging from the infinitesimal electron to the energy which moves the planets and suns, are all intangible, invisible factors.

All activities, whether chemical, vital or mental, operate invisibly, as observed in chemical affinity, in energy, in plant life, in animal life, in intelligence and mentalization. So in every department of our manifest physical nature it is evident that all elements have their root and permanence in the invisible. The invisible is the source of the visible.

Thus when we realize that the objective is only a combination of invisible substances and forces, the existence of an unseen world is readily comprehensible. Considering the wonderful advancement of science into the field of nature’s finer forces, it is inconceivable that any thinking mind can fail to recognize the rationale of the independent existence of the human spirit apart for the physical body. No subject has been better authenticated through the ages and in all literature than that of spirit existence and a future life.

Fiske, the historian, says: “Among all races of men, as far as can now be determined, ancestor worship” (contact with the spirits of the departed) “was the earliest form of worship. . . . prevailing in Africa, Asia, China, Japan, among the Aryans of Europe and the American Indian tribes.” Allen, in his History of Civilization writes: “Tribes the world over are found to have ideas of a human soul, a spirit world, and generally a belief in immortality. Savages consider the next life simply a continuation of this; they also recognize another self which has mysterious powers. Death is the abandoning of the body by this mysterious other self, which is conceived of as still existing in the near neighborhood.

The loves and hates of this world are transferred to the spirit world.” Confucius said: “Bemoan not the departed with excessive grief. The dead are devoted and faithful friends; they are ever associated with us.” The writers of classic times—Socrates. Herodotus, Sophocles, Euripides, Plato, Aristotle, Horace, Virgil, Plutarch, Josephus, Maximus of Tyre repeatedly refer to spirit existence as a well-known fact. Cicero wrote: “Is not almost all heaven filled with the human? Those very gods themselves had their original here below, and ascended from hence into heaven.” That early Christianity recognized spirits is too well authenticated in the writings of St. Anthony, Tertullian, Origen and their contemporaries to require emphasis.

The Bible is replete with references to spirit existence. “We also are compassed about with so great a cloud of witnesses.” Heb. 12:1. “Beloved, believe not every spirit, but try the spirits, whether they are of God.” 1 John 4:1. “The spirits of just men made perfect.” Heb. 12:23. “There is a natural body and there is a spiritual body . . . First that which is natural, and afterward that which is spiritual.” 1 Cor. 15:44, 46. Many other similar biblical citations might be given.

Swedenborg contributed volumes on this subject. Dr. Samuel Johnson said: “I do not believe in spirits-I have seen too many of them.” John Wesley wrote in the Invisible World: “It is true that the English in general-indeed most of the men of learning in Europe-have given up all accounts of witches and apparitions as mere old wives’ fables. I am sorry for it, and I willingly take this opportunity to offer my solemn protest against this violent compliment which so many that believe in the Bible pay to those who do not believe it. Such belief is in direct opposition, not only to the Bible, but to the suffrage of the wisest and best of men in all ages and nations. They well know that the giving up of witchcraft is in effect giving up the Bible.” That psychic phenomena occurred at the house of Mr. Samuel Wesley, father of Rev. John Wesley, at Epworth, and continued with noises and disturbances of various kinds for many months, is well known.

Shakespeare, Milton, Wordsworth, Tennyson, Longfellow, and many other poets wrote with profound understanding of the continued existence of man.

Dr. Thomas J. Hudson, author of The Law of Psychic Phenomena, wrote: “The man who denies the phenomena of spiritualism today is not entitled to be called a skeptic, he is simply ignorant.” The Rev. Dr. George M. Searle, Rector of the Catholic Church of St. Paul the Apostle, New York City, said: “The reality of the existence of spirits in modern spiritism is no longer an open question, even among scientific men who have examined the subject. Anyone who considers the manifestation of them as mere humbug, trickery or delusion, is simply not up to date.” “In our times no one denies the real existence of spiritualistic facts, except a few who live with their feet on the earth and their brains in the moon,” wrote G. G. Franco, S. J., in Civilta Cattolica. “Spiritistic phenomena are external facts which fall within the range of the senses and can easily be observed by all, and when such facts are attested by so many well informed and credible witnesses, it is useless, as well as foolish and ridiculous, to fight against proved evidence. The facts remain assured, even for reasonable men.” The spiritual world and the physical world are constantly intermingling; the spiritual plane is not a vague intangibility but is real and natural, a vast zone of refined substance, of activity and progress, and life there is a continuation of life in the physical world. On the physical plane of expression the soul obtains knowledge through experience and contact with objective things, and intelligence finds itself by manifesting through physical organs; in the spiritual plane progression of the individual continues, the mind unfolding along lines of reason, through spontaneity of service, the attainment and appreciation of high ideals and an ever broadening conception of life’s purpose.

The change called “death,”—the word is a misnomer—universally regarded with gloomy fear, occurs so naturally and simply that the greater number, after passing out of the physical are not aware that the transition has been made, and having no knowledge of a spiritual life they are totally unconscious of having passed into another state of being.

Deprived of their physical sense organs, they are shut out from the physical light, and lacking, a mental perception of the high purpose of existence, these individuals are spiritually blind and find themselves in a twilight condition—the “outer darkness” mentioned in the Bible— and linger in the realm known as the Earth Sphere.
Death does not make a saint of a sinner, nor a sage of a fool. The mentality is the same as before and individuals carry with them their old desires, habits, dogmas, faulty teachings, indifference or disbelief in a future life. “As a man thinketh in his heart, so is he.” Prov. 23:7.

Assuming spirit forms which are the result of their thought life on earth, millions remain for a time in the earth sphere, and often in the environment of their earth lives, still held by their habits or interests.

“Where your treasure is there will your heart be also. Matt. 6:21.

Those who have progressed to the higher spirit world ever endeavor to enlighten these earthbound spirits, but the latter, due to preconceptions concerning the hereafter, labor under the delusion that the departed are “dead,” or are “ghosts,” and often refuse to recognize their friends or to realize their own condition.

Many are in a state of heavy sleep, others are lost or confused; troubled minds may be haunted by fear of the strange darkness, those conscience stricken suffer in anguish or remorse for their, earth conduct; some, impelled by selfish or evil inclinations, seek an outlet for their tendencies, remaining in this condition until these destructive desires are outgrown, when the soul cries out for understanding and light, and progressed spirits are able to reach them and aid them.

Lacking physical bodies through which to carry out earthly propensities many discarnate intelligences are attracted to the magnetic light which emanates from mortals, and, consciously or unconsciously, attach themselves to these magnetic auras, finding an avenue of expression through influencing, obsessing or possessing human beings. Such obtruding spirits influence susceptible sensitive’s with their thoughts, impart their own emotions to them, weaken their will power and often control their actions, producing great distress, mental confusion and suffering.

These earthbound spirits are the supposed “devils” of all ages; “devils” of human origin, by-products of human selfishness, false teachings and ignorance, thrust blindly into a spirit existence and held there in a bondage of ignorance.

The influence of these discarnate entities is the cause of many of the inexplicable and obscure events of earth life and of a large part of the world’s misery. Purity of life and motive, or high intellectuality, does not necessarily offer protection from obsession; recognition and knowledge of these problems are the only safeguards.

The physical conditions permitting this impingement are varied; such encroachment is often due to a natural and predisposed susceptibility, a depleted nervous system, or sudden shock. Physical derangements are conducive to obsession, for when the vital forces are lowered less resistance is offered and intruding spirits are allowed easy access, although often neither mortal nor spirit is conscious of the presence of the other.

This encroachment alters the characteristics of the sensitive, resulting in a seemingly changed personality, sometimes simulating multiple or dissociated personalities, and frequently causes apparent insanity, varying in degree from a simple mental aberration to, and including, all types of dementia, hysteria, epilepsy, melancholia, shell shock, kleptomania, idiocy, religious and suicidal mania, as well as amnesia, psychic invalidism, dipsomania, immorality, functional bestiality, atrocities, and other forms of criminality.

Humanity is surrounded by the thought influence of millions of discarnate beings, who have not yet arrived at a full realization of life’s higher purposes. A recognition of this fact accounts for a great portion of unbidden thoughts, emotions, strange forebodings, gloomy moods, irritabilities, unreasonable impulses, irrational outbursts of temper, uncontrollable infatuations and countless other mental vagaries.

The records of spirit obsession and possession extend from remotest antiquity to modern times. Dr. Tyler, the noted English Anthropologist, in his Primitive Culture, says: “It is not too much to assert that the doctrine of demoniacal possession is kept up, substantially the same theory to account for substantially the same facts, by half the human race, who thus stand as consistent representatives of their forefathers back in the primitive antiquity.” In Muller’s Urreligion we find: “The general belief of the barbaric world today is that such attacks as epilepsy, hysteria, delirium, idiocy and madness are caused by some demon gaining control of the body.” Homer referred repeatedly to demons and said: “A sick man pining away is one upon whom an evil spirit has gazed.” Plato held that demons obsessed mortals.

Socrates speaks directly of demons influencing the possessed (insane). Plutarch wrote: “Certain tyrannical demons require for their enjoyment some soul still incarnate; being unable to satisfy their passions in any other way, incite to sedition, lust, wars of conquest, and thus get what they lust for.” Josephus says: “Demons are the spirits of wicked men.” Obsessing or possessing spirits are frequently mentioned both in the Old and New Testaments. In 1 Samuel 16:23, we read: “David took an harp, and played with his hand: so Saul was refreshed, and was well, and the evil spirit departed from him.” So common was the belief in spirits and spirit obsession in the time of the apostles that the ability to cast out evil spirits was considered one of the most important signs of genuine discipleship, and it must be admitted that a considerable portion of the work accredited to Jesus was the casting out of demons.

A few quotations from the New Testament will suffice. “Jesus gave his twelve disciples power against unclean spirits, to cast them out.” Matt. 10:1. “’Jesus preached . . . and cast out devils.” Mark 1:39. “A certain man which had devils long time . . . Jesus had commanded the unclean spirit to come out of the man ... He that was possessed of the devils was healed.” Luke 8:27, 29, 36. “Vexed with unclean spirits.” Luke 6:18. “The evil spirits went out of them.” Acts 19:12.

“Master, I have brought unto thee my son, which hath a dumb spirit ... And he asked his father: How long is it ago since this came unto him? And he said, Of a child ... Jesus rebuked the foul spirit, saying unto him, Thou deaf and dumb spirit, I charge thee, come out of him, and enter no more into him. And the spirit cried, and rent him sore, and came out of him: and he was as one dead; insomuch that many said, He is dead. But Jesus took him by the hand, and lifted him up; and he arose.” Mark 9:17, 21, 25-27. (Similar occurrences are not at all uncommon in psycho- pathological research.) Among the writers of early Christianity we find that St. Anthony says: “We walk in the midst of demons, who give us evil thoughts; and also in the midst of good angels. When these latter are especially present, there is no disturbance, no contention, no clamor; but something so calm and gentle it fills the soul with gladness. The Lord is my witness that after many tears and fasting I have been surrounded by a band of angels, and joyfully joined in singing with them.” Tertullian with authority challenged the heathery to a trial of superiority in the matter of casting out demons. Minucius Felix, a Roman advocate and apologist, wrote in Octavius:
“There are some insincere and vagrant spirits, degraded from their heavenly vigor . . . who cease not, now that they are ruined themselves, to ruin others.” Dr. Godfrey Raupert, of London, who several years ago was especially delegated by Pope Pius X to lecture to Catholic audiences in America on Spiritualism, said in substance: “It is no longer possible to put the subject of psychic phenomena aside. The scientific men all over the world have recognized spiritism as a definite and real power, and to shelve it is a dangerous policy. Consequently the Pope has asked me to tell Catholics the attitude to take toward the subject ... The Church admits the reality of these spiritistic phenomena and their external intelligences, in fact, it has always admitted their reality. The problem at present is to discover the nature of the intelligence. We are now on the borderland of new discoveries which may revolutionize the world.

It is not the time yet for an explanation of all the phenomena. We must suspend our judgment until the subject is better known. The study of spiritism is a new one and therefore dangerous . . . A partial knowledge of the subject may cause grave dangers.” (Resulting in obsession or possession.) “There is no doubt about the fact of diabolical obsessions in the olden time. That the Church (Catholic) recognizes the possibilities is evidenced by the rules prepared for exorcising,” is the quoted statement of Monsignor Lavelle, Rector of St. Patrick’s Cathedral, New York.

Julian Hawthorne wrote, in one of the leading newspapers: “Thousands of evil-minded and evil-acting men and women die every day.

What becomes of their souls, or spirits? They want to get back here… the increasing boldness and frequency with which they take advantage of their opportunities is illustrated in many ways. . . Two acts of defense are open to us. We may stop the source of supply of these undesirable visitors and we may close the doors.” Dr. Axel Gustafson’, who publicly acclaimed his views regarding the fact of spirit obsession, in quoting cases which had come to his attention, said: “The spirits of the revengeful have power after death to enter into and possess the living under certain conditions.” Prof. Herbert L. Stetson, of Kalamazoo College, Michigan, stated, in a lecture at the University of Chicago: “Demon obsession is no myth; illness is often due to demoniacal possession.

Belief in demons is widespread.” “I often see the spirits who cause insanity,” is the statement of Dr. E. N. Webster, of the mental section of the American Medical Association.

“At times I even hear their voices. Insane persons who are spoken of as hopelessly insane are frequently lost under the overwhelming control of a spirit or crowd of spirits. We frequently find by post-mortem examination that no physical disorder exists in the brain or nervous system of such persons.” Prof. William James wrote in Proceedings S. P. R.: “That the demon theory will have its innings again is to my mind absolutely certain.

One has to be ‘scientific’ indeed, to be blind and ignorant enough to suspect no such possibility.” Prof. James H. Hyslop, while editor of the Journal of the American Society for Psychical Research, wrote: “There is growing evidence of the fact of obsession which lies at the basis of much insanity and can be cured. The medical world will have to wake up and give attention to this problem or materia medica will lose control of the subject.” In one of Prof. Hyslop’s latest books, Contact with the Other World, we find the following: “The existence of evil spirits affecting the living is as clearly taught in the New Testament, and implied in the Old Testament, as any doctrine there expounded. . . . The term obsession is employed by psychic researchers to denote the abnormal influence of spirits on the living…. The cures effected have required much time and patience, the use of psychotherapeutics of an unusual kind, and the employment of psychics to get into contact with the obsessing agents and thus to release the hold which such agents have, or to educate them to voluntary abandonment of their persecutions. . . . Every single case of dissociation and paranoia to which I have applied cross-reference has yielded to the method and proved the existence of foreign agencies complicated with the symptoms of mental or physical deterioration.

It is high time to prosecute experiments on a large scale in a field that promises to have as much practical value as any application of the scalpel and the microscope.” In Modern Psychical Phenomena, Dr. Hereward Carrington states: “It is evident . . . that spiritual ‘obsession’ is at least a possibility which modern science can no longer disregard, while there are many striking facts in its support. This being so, its study becomes imperative— not only from the academic viewpoint but also because of the fact that hundreds and perhaps thousands of individuals are at the present moment suffering in this manner, and their relief demands some immediate investigation and cure. Once grant the theoretical possibility of actual obsession, and a whole vast field of research and investigations is opened up before us which demands all the care, skill and patience which modern enlightenment and psychological understanding can furnish.” Never before in the history of medical science has there been such widespread interest, by the public at large, as well as by medical men and public officials, in the subject of the cause, treatment and cure of nervous and mental diseases. Statistics show that insanity is increasing with alarming rapidity everywhere, yet medical experts differ widely as to the causes of mental deterioration, and science is not yet in possession of knowledge of the exact etiology of functional insanity.

“The whole world will go mad before long,” declared Dr. Winslow of England.

The greater number of neurologists and alienists entertain the belief that the active and underlying cause of insanity has its origin within the deranged nervous system, but very little as yet is actually known of the true cause.

Dr. W. M. L. Coplin, Director of the Bureau of Health and Charities, Philadelphia, Pennsylvania, said—”Insanity, in most cases, is unaccompanied by any perceptible change in the brain structure. The brain of the patient, when examined under a microscope, shows absolutely nothing which differs in any way from the appearance of the brain of the perfectly sane person. It is therefore evident that the insanity might be due to toxemia, the effect of some subtle organism in the nature of bacilla…. Something causes insanity but what it is, we do not yet know.” Dr. Britton D. Evans, Superintendent of the Morris Plains, New Jersey, Insane Asylum, stated: “Brain tumor or brain fever may not affect the mind…. A man may have trouble of the brain and still have a normal mind.” Dr. Th. Ziehen, a noted German alienist, and an authority on hysteria, wrote: “For many functional neuroses there is as yet no accurate limitation and definition. As pathological anatomy does not aid us, no uniform and exclusive cause for hysteria can be demonstrated.” Dr. William Hanna Thomson, physician to the Roosevelt Hospital and Professor of the Practice of Medicine and Diseases of the Nervous System, New York University Medical College, in referring to Tuke’s Dictionary of Psychological Medicine, asserted that: “The contributors to this great encyclopedia are from the most eminent professors, experts, and superintendents of insane asylums in Great Britain, the United States, France, Germany, Hungary, Belgium, Denmark, Switzerland and Russia. In the articles by the writers on kleptomania, dipsomania, chronic mania, etc., there is not a word about the pathological anatomy, (because none can be found). Just so it is in the article on melancholia, puerperal insanity, katatonia, circular insanity, homicidal insanity or epileptic insanity; in none of these is there a word about pathological anatomy, for the sufficient reason that not one of these forms of insanity shows any pathological or diseased condition in the brain different from the sound brain of a healthy man killed in an accident.” He also said: “It is high time that we now look in the direction of toxemia (or blood poisoning) for the explanation of the insanities which produce no changes whatever in the brain.” Recent announcement was made that a large percentage of cures reported by the New Jersey State Hospital for the Insane at Trenton were effected by the removal of diseased teeth, tonsils or affected organs. In a resume of the Trenton method, Dr. R. S. Copeland wrote: “The hypothesis upon which this treatment is founded is that insanity is a toxemia or poisoning due to germ infection in some part of the body. If this is true it follows that removal of the infected tissue, when the case has not gone too far, will be followed by disappearance of the mental disturbance.” When statistics compiled by the United States Government, as well as by others, show that the increase in the number of the insane is proportionately greater than the increase of the general population, it seems incongruous to credit decayed teeth and diseased tonsils as being primary causes of mental unbalance at this time when dental and surgical attention is so general, whereas, the facts are that when dentistry was little known and practiced, and people went about with all conditions of decayed teeth, insanity was less prevalent than now.

Without attempting to discredit the Trenton reports, it may be stated that our experience has shown that in many cases of mental derangement, although the patient bad badly decayed teeth, mental balance was fully restored by dislodging the obsessing spirit before any attention was given to the teeth.

Since it has been found that obsessing spirits are sensitive to pain, I am constrained to suggest that such cures as announced by the Trenton Hospital may, at least in part, be due to the fact that intruding spirits were dislodged, by dental or surgical interference.

To the investigator in Abnormal Psychology on the spiritistic hypothesis much of the symptomatology of the “War Neurosis’’ or shell shock,— excepting cases of malingering—as recorded by Dr. F. E. Williams, Acting Medical Director, National Committee for Mental Hygiene, New York City, suggests obsession or possession by spirits of dead soldiers, unconscious of their transition, as the exciting cause. This is indicated by “delirium, hallucinations, anxiety states, functional heart disorders, paralysis, tremors, gait disturbances, convulsive movements, pain, anesthesia, hyperesthesia, blindness, disorders of speech, etc.” The spirit hypothesis regarding War Neurosis is further evidenced by the rapid recovery of patients under severe electrical treatment— (driving out obsessing entities?), as instituted by Dr. Vincent who, Dr. Williams stated, would cure in a few hours Patients that had been in the care of other psychiatrists for months, and would have them walking about and climbing ladders.” The above theory is also favored by Dr. Williams’ further statements that: “This neurosis is rare among prisoners who have been exposed to mechanical shock . . . as well as among wounded exposed to mechanical shock…. Severe injury to the central nervous system and brain is not accompanied by symptoms found in shell shock…. Success attends the therapeutic measures employed for the psychological rather than the mechanical side. . . . Diagnosis should be made and treatment begun at once before the shell shock”—(obsession)—”becomes a fixed psycho-neurosis.” Newspapers recently reported the case of a young man, Frank James, a boy thug of New York City, who, after a fall from a motorcycle when ten years old, changed from a cheerful, affectionate and obedient child into a surly, insolent boy, developing into a confirmed robber and criminal.

After several terms in the reformatory and five years in Sing Sing prison he was declared hopelessly insane, and sent to the State Insane Asylum. Frank James, however, escaped, and when pursuers attempted his capture, was hit on the head with a club, and falling unconscious, was taken to a hospital.

The next morning the boy awoke, extraordinarily changed; he was gentle and deferential, showing no further indications of an unbalanced mind, and from that time exhibited not the slightest impulse to commit crime of any kind. The article concludes: “Just what happened to the mechanism of the boy’s brain is not entirely understood by medical men.” How explain such a case on the toxemia theory? Could a blow on the head eradicate the supposed toxemia and restore mental balance? The simple explanation from our viewpoint would be that, following the shock of the boy’s fall, an obsessing spirit criminal had taken control of the boy, and that the blow from the club on the man’s head, with its accompanying pain, caused the obsessing entity to become dislodged.

The success credited to hydrotherapy as practiced in institutions for the insane, especially when a strong stream of water, or a continuous bath, is used, can also be accounted for by the dislodgment of obsessing entities, who object to the discomforts incident to such treatment.

Dr. Prince, in the Journal of Abnormal Psychology, wrote: “If we are to establish sound principles underlying the mechanism of the mind we must correlate the findings of all methods of research, experimental as well as clinical, and give due consideration to the results obtained by all competent investigators.” After careful elimination of all superstitious notions and absurdities adherent to the subject of Normal and Abnormal Psychology, excluding also febrile and idiopathic psychoses or idiosyncrasies, as well as all neuro-pathogenic psychoses, there still remains a residuum of abnormality in a majority of cases of mental aberrations.

That alienists of renown and the foremost authorities widely disagree as to the cause of insanity is sufficient reason for thinking men to investigate any theory which promises to lead to results, regardless of personal or popular prejudice. The situation which confronts us is a serious one, and nothing but the broadest toleration and liberality can cope with it. Since insanity is chiefly a manifestation of mental or psychological disturbance—a Psychic neurosis—the symptomatology therefore should offer a guidance in ascertaining the etiology, and assist as well in arriving at a solution of the mental pathology.

This proposition, however, necessitates not only research and study of Normal and Abnormal Psychology but, in order to have a complete premise, also implies the recognition of the duality of man-matter and spirit, physical and spiritual.

Insanity is not a stigma; the public attitude toward this affliction should be one, not of aversion but of understanding, and a realization of the close inter-relationship of the visible and invisible worlds.

Spirit obsession is a fact—a perversion of a natural law—and is amply demonstrable. This has been proven hundreds of times by causing the supposed insanity or aberration to be temporarily transferred from the victim to a psychic sensitive who is trained for the purpose, and by this method ascertain the cause of the psychosis to be an ignorant or mischievous spirit, whose identity may frequently be verified.

By this method, and without detriment to the psychic, it has also proven possible to relieve the victim, as well as release the entity from its condition of spiritual darkness through an explanation of the laws governing the spirit world, which the experiences to follow will demonstrate.

Inter-communication between the visible and invisible worlds is a natural privilege and is established through a person of a certain psychic constitution, capable of acting as an intermediary, through whom discarnate intelligences can readily come en rapport with the physical plane. Of the various phases of contact the most valuable for research purposes is that of unconscious trance, whereby direct communication may be established with the invisible world and the mental condition of discarnate intelligences, either advanced or ignorant, may be ascertained.

Ignorant psychic experimentation may prove injurious when dabbled in by those who neglect the necessary precautions and lack understanding of the laws which govern the subject, just as ignorance and disregard of the laws governing everyday life may prove dangerous. The misuse of a thing is no argument against its use.

Psychical Research belongs especially to the domain of science; common sense and discrimination are essentials in all such experimental work, as well as a thorough mastery of the laws involved. Under these conditions scientific research becomes an invaluable factor in the investigation of Spiritual Science.
